- The parameter n_jobs has been deprecated from the classes :class:`~imblearn.over_sampling.ADASYN`, :class:`~imblearn.over_sampling.BorderlineSMOTE`, :class:`~imblearn.over_sampling.SMOTE`, :class:`~imblearn.over_sampling.SMOTENC`, :class:`~imblearn.over_sampling.SMOTEN`, and :class:`~imblearn.over_sampling.SVMSMOTE`. Instead, pass a nearest neighbors estimator where n_jobs is set. :pr:`887` by :user:`Guillaume Lemaitre <glemaitre>`.
- The fitted attribute estimator_ in :class:`~imblearn.under_sampling.CondensedNearestNeighbour` has been deprecated and will be removed in 0.12. Instead, use the n_neighbors_ fitted attribute. :pr:`891` by :user:`Guillaume Lemaitre <glemaitre>`.
- Add support to accept compatible NearestNeighbors objects by only duck-typing. For instance, it allows to accept cuML instances. :pr:`858` by :user:`NV-jpt <NV-jpt>` and :user:`Guillaume Lemaitre <glemaitre>`.
- Add support to accept compatible KNearestNeighbors objects that can be clone and have an attribute n_neighbors. :pr:`891` by :user:`Guillaume Lemaitre <glemaitre>`.
